CIBERSORT demonstrated that high infiltration of Macrophage M1 (p<0.001) and Follicular Helper T cells (p<0.001) in Grade 3 tumors in all cohorts. Infiltration of NK cells was inconsistent between the cohorts although CD8+ T cells were not significantly elevated in Grade 3 tumors. Grade 3 tumors were associated with significantly more TCR diversity (p<0.001), reflecting higher neoantigen load in Grade 3 tumors (p=0.02) in the TCGA cohort. Further, CYT was also significantly elevated in Grade 3 tumors in all cohorts.
